displays  the  entities  that  may  be  managed  by  the  TK37XX  Host  Interface,  including  the  OLT,  ONUs  and  Logical 
Links.  This  sash  window  shall  be  referred  to  as  the  Element  Status  Window.  Left  clicking  on  an  entity  with  the 
mouse will open a tabbed panel in the upper right sash window that may be used to manage the entity. This sash 
window  shall  be  referred  to  as  the  Entity  Management  Window.  The  bottommost  sash  window  is  used  for  the 
purpose of logging the host interface message that are sent and received by the GUI, and shall be referred to as 
the Message Log. The Message Log displays the commands that are sent and received from the GUI as well as the 
raw bytes sent and received by the physical layer interface. 

 

 

2.1 Basic Structure of GUI Software

 

The  GUI  software  breaks  down  into  4  logical  layers  the  first  layer  is  the  physical  interface.  The  operating  system,  or  driver 

resource, used to send and receive the raw Host Interface messages. The next layer consists of the underlying messaging system 
used by the GUI. This layer is responsible for parsing and queuing of Host Interface Messages as well as providing reliability. The 
next  layer  is  the  application  layer.  This  layers  responsibility  is  to  display  the  GUI  windows  and  provide  services  such  as  alarm 
auditing. 

 

2.2 GUI Start Up Sequence

   

When the user invokes the    EponSystemApp.exe by double clicking on the T icon the GUI will perform the following functions: 

EponSystemApp.exe   

Step 0: 

Attempt  to  establish  a  UDP  connection  to  the  TK3721.  This  process  will  continue  indefinitely  or  until  the  connection  is 

established. 

Step  1: 

After  the  connection  is  established  the  GUI  will  test  the  interface  by  attempting  to  send  and  receive  a  host  interface 

message. The natural choice (and the choice that the GUI will use) is the Get OLT Information. This message contains information 

about the TK3721 that the host may use to identify product version information. 

Step  2: 

Once  the  interface  has  been  established  the  next  step  the  GUI  shall  perform  is  to  obtain  the  list  of  discovered  links.  It 

should be noted that once the interface is detected the GUI shall initiate a process to handle autonomous events. Receiving an
